Capability · Coupled

Two-way fluid-structure interaction across the full envelope

Aeroelasticity, hydroelasticity, sloshing and seal deflection resolved with a tightly coupled solver loop. Run hundreds of flight or duty points overnight and get flutter margins, deflection maps and fatigue spectra instead of a single hero simulation.

Capabilities

Everything the study needs, inside one solver loop

01

Flutter & divergence margins

Modal and time-domain flutter analysis with damping tracking across Mach and altitude sweeps.

02

Gust & manoeuvre loads

Discrete and continuous turbulence load cases mapped straight onto the structural model.

03

Sloshing & free surface

VOF free-surface coupling for fuel tanks, coolant reservoirs and battery immersion systems.

04

Seal & membrane deflection

Large-deformation contact for elastomeric seals, diaphragms and flexible ducting.

05

Mesh morphing

Radial-basis-function morphing keeps the fluid mesh valid under large structural displacement.

06

Aerofoil aeroelastics (live in the studio)

Vortex-panel aerodynamics coupled to a torsional root spring — twist, tip deflection and divergence margin solved interactively.

07

Hypersonic re-entry (live in the studio)

Sphere-cone shock layer with modified-Newtonian pressure, Fay-Riddell stagnation heating and radiative-equilibrium wall temperature.

08

Multi-fidelity surrogates

MF-DNN surrogates trained on cheap analytic data plus a handful of full-solver runs predict the envelope in milliseconds.

09

Rotating machinery

Blade untwist, tip-clearance and forced-response analysis for fans, compressors and turbines.

Workflow

01

Couple the models

Map the CFD surface to the structural model with conservative load and displacement transfer.

02

Define the envelope

Parametrise Mach, altitude, angle of attack, RPM or flow rate as a sweep, not a single point.

03

Run coupled

Implicit sub-iterations with automatic under-relaxation and per-point convergence monitoring.

04

Extract margins

Damping trends, deflection envelopes and stress spectra rolled up into a certification-ready report.
